Method Detail

billboarding

public void billboarding()

Overrides:

billboarding in class Billboarder

cake

public void cake()

Which pieces of the cake has to be chosen, depends on the actual side of the camera position.

cake

public void cake(int side)

Rotates two HalfSpaces around z-axis. Both HS are twisted. The angle between HS is the same like one rotation-step angle. After the intersection of these two HS, exist a new space. All objects inside in this space will set to a visible Layer. All objects outside will set to an invisible Layer. Which Layer is visible or not can defined with #setLayer(). From the top of view, it looks like a piece of a cake.

Parameters:

side - Which two pieces will be visible.

setCenterDim

public void setCenterDim(float centerWidth,
                         float centerHeight)

The center of the cake is a line which shows in positive z direction. The line starts at the origin of the global coordinates-system. The length of a line is defined by centerHeight. All objects with a distance less then centerWidth are visible too. So the center is a quasi cylinder.

Parameters:

centerWidth -

centerHeight -

setLayer

public void setLayer(int visible,
                     int invisible)

Defined which layer is for the visible and which for the invisible objects. The default-value for visible is 0 and invisible 15.

Parameters:

visible - The Number of the visible layer in the 3D-view

invisible - The Number of the invisible layer in the 3D-view

setRunLater

protected void setRunLater()

Description copied from class: Billboarder

When a Billboard-Render-Thread is finished, the implementation of this method will be executed later.
